摘    要:目的  研究血管紧张素转化酶抑制剂(ACEI)对过量饮酒大鼠心脏功能和结构的保护作用。方法  30只大鼠随机分为对照组、酒精组和ACEI组,每组10只。酒精灌胃建立动物模型,并给予ACEI类药物作为保护剂,用超声心动图及超微病理技术观察大鼠心脏功能和结构改变。结果  酒精组左室舒张末期内径高于对照组[(6.86±0.64)mm vs(6.29±0.28)mm, P<0.05],收缩末期内径高于对照组[(3.45±0.32)mm vs (2.95±0.25)mm, P<0.05];两组收缩功能参数左室射血分数、每搏输出量、短轴缩短率无统计学差异(P>0.05);舒张功能参数二尖瓣内环舒张早期晚期速度比(Ea/Aa)低于对照组[(0.642±0.126) vs(1.276±0.083), P<0.05]。而ACEI组各参数相对于对照组没有明显改变(P>0.05)。病理形态学观察可见,酒精组线粒体水肿、嵴和膜大部分溶解消失。ACEI组线粒体少部分嵴和膜溶解,损伤程度较酒精组轻。结论  ACEI类药物对过量饮酒大鼠的心肌具有一定的保护作用。

Abstract:Objective To investigate the protective effect of (ACEI) on cardiac function and structure in excessive alcohol-consumption rats. Methods 30 rats were randomly divided into three groups:the control group,the alcohol group and the ACEI group,10 for each group. They were arranged for intragastric administration of alcohol,and given ACEI as a protector. Then echocardiography and an ultrastructural exam were performed to assess cardiac dysfunctions. Results The left ventricular end-diastolic dimension (LVEDd) a...
